HARMONY CHART.

Application led November 7,1924. Serial'No. 748,305.

imperforate base-sheet, which 4are mounted inthat order beneath a perforated superimposed sheet (called herein for convenience a view-sheet) on which are indicated the signature-key window and windows through which the corresponding chords are visable. By the use of my invention it is possible to presentv to the eye of the user (a) any desired signature key; (b) the major scale of that key; (c) the intervals of said major scale, formed from the different degrees of the preceding major scale; (d) the minor intervals formed from said major in- -tervals; (e) the diminished and augmentedy intervals formed from said major Aand minor intervals; (f) the triads constructed from said major and minor intervals, and their inversions; (g) and important seventh 5 chords and inversions.

In accomplishing this end each of the three sheets contributes to make the complete display of the desired facts, as to any key, possible in a singleorganization.

' Description.

dow vindicated as showing the signature'key.

When the sheets A, B and Care in their initial Lposition the ',keydisplayed will be Ot or C, and'displayed'through the other perforations. insheet A iv'illbe the several chords of that key of `C indicated bythe ilettering on sheet A.

`Sheets A, B and C are so mounted in a supporting frame' Dthat sheet -B may -be shifted'laterally tochange thesignature key .displayed as above from Sharps toilats7 and :that shift will also produce the desired changes of chords displayed.

`r`Sheets A:and D arei in `fixed relationship; sheetfB is movable right or left solely tothe f extent offshiftingv the' display of the -chart yfrom Sharps toy flats or vice versa. vSheets B and C are movable `vertically together to display in succession through the openings in the view-sheet A all the keys of the musical scale and all the Sharps and flats of those keys, with their appropriate chords.

The openings in the view-sheet A may be irregular in form as shown at 10, having an inwardly projecting tongue 11, the use of which is to cover the sharp or fiat opposite the key (as shown on sheets B and C,) displaying such key as natural.

The base-sheet C has upon its front face a thickened border 14.- forming a receptacle for the mask-sheet B; that border 14 is cut away at its ends to form the slots 13 through which the ears 12 of the mask-sheet B extend; by which means the mask'sheet B is shiftable upon the face of the base-sheet C (see Figs. 8 and 9).

The supporting frame D is open at its top (see. Fig. 1l); ythe View sheet A is fixedly mounted on said frame D, while the basesheet C (carrying with it the mask-sheet B) is vertically adjustable within the trame l). This vertical adjustment permits in succession the display, through the signaturekejf-ivindou* 15 of view-sheet A, ot all ot the numerals O to 7 which are inscribed in the column marked 1G of the mask-sheet B (se-e Fig. 2). While that signature-key will be indicated as dat by the exposure of one of the characters formed in the column i7 ot mask-sheet B (see Fiji. 2) or as sharp, by the exposure of one ot the sharp characters 'found in the column 18 of the base-sheet C (see Fig. 3

lilith each shirt of the signature key, the appropriate chords are displayed through the apertures in the view-sheet A, in the manner illustrated in Figs. 5 and G.

he manner in which the sheets L and B are apertured, sheet A along horizontal lines and sheet B on vertical lines, to secure alinement with the vhorizontal and vertical lines of inscription on the base-sheet C is Jfully shown in the drawings.

l am aivare that music-charts or harmonycharts exist in the prior art in which a. perforated tace-plate is combined 'ith a single impertorate sheet shittably mounted beneath said tace-plate, for the purpose of eilecting such key-and-chord variations as may he accomplished by the use ot said fixed tace-plate and a single impertorate sheet; and I therefore do not claim such a struct-ure as my invention. TWhat l do claim comprises a suitably inscribed front perforated Window-sheet or view-sheet, an imperforate suitably-inscribed base-sheet vertically adjustable and mounted so that its markings may be. read through the Windows ot the view-sheet, and a suitably inscribed slotted mask-sheet horizontally adjustable and mounted between the view-sheet and basesheet; as defined in the appended claims.

As shown in Fig. 2, the mask-sheet B is arranged to carry the sharp and flat inscriptions shown thereon in vertical columns, which are so disposed as to register with the columns of key letters shown on the base-sheet C (see Fig. 3) to indicate such keys as sharp or ilat, when viewed through the apertures of the view-sheet A. key is effected by the lateral shitt oft the mask-sheet B upon the base-sheet C. The particular' arrangement of inscriptions upon sheets A. B and C and apertures in sheets A and B which I prefer is that illustrated in Figs. l, Q and 3; but various alterations may be made therein, and additions thereto may be made, or portions omitted, Without departing from my invention as dciined in he claims ot this speciiication.

l claiml. harmony chart comprising a Viewieet. a mask-sheet, a. base-sheet, and suporting means therefor, and a supporting a'ne wherein seid sheets are mounted.

A harmony chart comprising a Viewsheet; supporting frame upon which said view-sheet is fixed: a base-sheet so mounted in said supperting;r frame as to be vertically y adjustable therein; and a mask-sheet so mounted upon said base-sheet as to be shii'ted laterally thereon.

harmony chart comprising' a viewsheet; a supporting frame upon which said view-sheet fixed; a base-sheet so mounted in said supportingr frame as to be vertically adjustable therein: and a mask-sheet so mounted upon said base-sheet as to be shifted laterally thereon. and to be carried vertically by the vertical movement of the base-sheet.

ln testimony whereof I have hereunto affixed my signature.
